The Notorious Kabay Homework Flood Earlier versions of this course were known for the amount of homework Visited Prof Post’s site and discovered that Kabay’s homework assignments were 5-10 times greater than the author’s own course assignments This year’s course will not be so grueling Reducing required homework to more manageable levels Still offering opportunities for extra credit for extra homework Can help students become highly skilled

Importance of Homework Theory isn’t enough Critically important that you learn to use a real DBMS Design Create Enter data Extract data Reports

The Term Project Small homework assignments drill individual skills Term project offers opportunity to integrate Semi-realistic experience will stand you in good stead Offer choice of projects to reflect diversity of class background May do more than one if you want more challenge By all means support each other to do better – discuss, share ideas But do not copy designs and code verbatim Do your own work once you have understood
